Refering to the above graphs, can anyone help explain the phenomenons of several stages labelled? (a,b,c,d,e,f,g,h,i,j)

thx for the help!

The grapsh show voltage versus position on a horizontal line going through the middle of the depicted objects, with "before" meaning without the presence of the second object in the middle or on the right in the diagragms, and after meaning with the presence of the second object. It seems the main idea is to show that the voltage doesn't change within a conductor. The first diagram shows the case where a hollow conducting object sets up up an opposing internal field.

Yes.
But I'd like to know every labelled phenonmenon in detail.
(and I know there're really a lot of questions =P)

## What is electric potential?

Electric potential is a measure of the electric potential energy per unit charge at a specific point in an electric field.

## How is electric potential different from electric field?

Electric potential is a scalar quantity that describes the potential energy of a charge at a specific point in an electric field, while electric field is a vector quantity that describes the force experienced by a charge at a specific point in an electric field.

## What is the unit of electric potential?

The unit of electric potential is volts (V), which is equivalent to joules per coulomb (J/C).

## How is electric potential calculated?

Electric potential is calculated by dividing the electric potential energy by the charge of the object. The equation for electric potential is V = U/Q, where V is the electric potential, U is the electric potential energy, and Q is the charge of the object.

## What is the difference between electric potential and electric potential difference?

Electric potential difference is the difference in electric potential between two points in an electric field, while electric potential is the electric potential at a specific point in an electric field.
